Ultra-high-speed frame thermal spraying (HP-HVOF spraying) - cermet spraying

What is ultra-high-speed frame thermal spraying (HP-HVOF spraying) - cermet spraying?

"Thermal spraying" is a technique that involves heating materials such as metals or ceramics, turning them into fine particles, and spraying them onto the surface of a substrate using a high-temperature, high-pressure gas flow or plasma. This process allows for the imparting of properties such as wear resistance, corrosion resistance, heat resistance, and thermal insulation to the surface of the substrate. Broadly, thermal spraying can be divided into two categories: one aimed at "high functionality" such as wear resistance, corrosion resistance, heat resistance, and rust prevention, and the other aimed at "repair and regeneration" of worn components. Thermal spraying has a wide range of applications as a surface treatment technology and contributes to improving product functionality and extending lifespan. "HP-HVOF thermal spraying" is one type of thermal spraying technology that utilizes a high-speed, high-temperature gas flow generated by mixing oxygen and fuel and combusting it under high pressure, primarily used for spraying coating materials such as cermets. Therefore, it is also referred to as cermet spraying. It is particularly used to form high-density and high-strength coatings, making it suitable for imparting properties such as wear resistance, corrosion resistance, and heat resistance. It is widely used in fields that require precise and high-performance coatings, playing a crucial role especially in components and structures used in harsh environments.

HVOF thermal spraying (High Velocity Oxy-Fuel spraying)

High-speed jet frame spraying using oxygen and fuel.

◆◇◆ What is HVOF Thermal Spraying ◆◇◆ It stands for High Velocity Oxygen Fuel. It refers to thermal spraying using a high-speed jet flame created by oxygen and fuel. A mixture of high-pressure oxygen and fuel gas is burned in a combustion chamber. The combustion flame is constricted by a nozzle, and the moment it exits into the atmosphere, a rapid gas expansion occurs, resulting in a supersonic jet. The thermal spray material accelerated by high kinetic energy forms a high-density coating with minimal oxidation or compositional changes.

HVOF thermal spraying (High Velocity Oxygen Fuel spraying)

It is a super hard coating technology that possesses a dense film characteristic with strong adhesion to the substrate, resulting in extremely high wear resistance and corrosion resistance.

"HVOF thermal spraying (High Velocity Oxygen Fuel spraying)" is a super hard thermal spray coating adapted for wear and corrosion resistance. Due to the smooth surface of the coating, it is easy to achieve a super mirror finish, and a thick film formation is also realized. The extremely high particle velocity (500–800 m/s) produces a coating with very high density and low porosity. Additionally, because the material is fed at ultra-high speed, the time it is exposed to the flame is minimized, allowing for the reduction of oxidation and alteration to a minimum. 【Features】 ■ High density ■ High adhesion ■ Oxidation and alteration suppression ■ Surface smoothness *For more details, please refer to the PDF document or feel free to contact us.
